Waste will kill ipv6 too

As a small local ISP, our upstream isn't willing to give us more than a
/48, their statement "Here's a /48 that will give you unlimited addresses
that you'll never run out of". Therefore we give businesses /60s and
residentials /64. If only we could do as suggested here and give everyone a
/48, hah. It would be awesome if we could get an AS number but as we're not
multihomed, nor big enough to warrant ARIN paying us attention, we're at
the mercy of our upstream who also unwilling to part with more than a
single ipv4 /24 at a $300/mo surcharge, and forcing us into buying ipv4
subnets that have been randomly blacklisted on sites such as HULU, netflix,
or others.

I agree with the sentiment that we should have only 48 bits in the
networking portion as that does allow a 48bit mac to exist. mac collisions
happen so little, that it would make more sense for DAD to step in if it
does occur. Most hardware addresses are changeable anyway and should
probably be changed if on the same network. I am inexperienced enough to
not understand any necessary usefulness of a /64 network mask over a /80.
